How to Tell If Your Window Tinting Is Legal (Without Getting a Fine!)

Driving with tinted windows can elevate your car’s aesthetics, enhance your privacy, and minimise glare. However, it is essential to ensure that your tint complies with UK laws, as non-compliance can result in fines or even cause you to fail your MOT test. Imagine being stopped by authorities or facing unexpected costs—all because your tints are too dark.

Scenarios like these can spark a moment of unease, making you pause and wonder, “Are my tints legal?” 

What the UK Law Actually Says About Window Tints

Window tinting regulations in the UK aim to maintain road safety by ensuring adequate visibility for drivers, especially at night. Overly dark tints can obstruct a driver’s view or prevent law enforcement from seeing inside the vehicle when necessary.

UK window tinting regulations strictly govern the level of tint allowed on the front windscreen and front side windows of vehicles, using visible light transmission (VLT) as the key metric. This refers to the percentage of light that can pass through a window.

For vehicles first used on or after 1 April 1985, the rules are as follows:

  • Front windscreen: Must allow at least 75% of light through.
  • Front side windows: Must allow at least 70% of light through.

Subsequently, for vehicles first used before this date, both the front windscreen and side windows must have a VLT of at least 70%.

Simple Ways to Check If Your Window Tint Is Legal

If you are unsure whether your window tinting Birkenhead complies with UK law, there are several methods to assess it. Here is how you can start:

Visual Inspection

While not definitive, a preliminary visual inspection can give you an initial indication of whether your tints might be too dark. Stand outside your vehicle during daylight hours and look at the front windscreen and front side windows. If they appear significantly darker than standard factory glass or make it difficult to see the interior clearly, they might be below the legal VLT percentages.

A useful comparison technique is to park your vehicle next to another car with standard factory glass. If your windows appear noticeably darker, particularly from the outside looking in, this could be a warning sign. However, remember that this method is subjective and can be influenced by lighting conditions and viewing angles.

Checking Documentation

If your window tint films were professionally installed, reviewing the documentation or certification provided by the installer is a good starting point. Reputable window tinting companies typically specify the VLT percentage of the film they have applied. This paperwork is invaluable, as it can quickly confirm whether your tinting adheres to legal requirements.

On the other hand, if you purchased the vehicle with pre-existing tints, try to determine whether they were factory-fitted or aftermarket installations. Factory-fitted tints generally comply with legal requirements.

However, if you installed the window films yourself without documentation of the VLT percentage, consider seeking a professional assessment. Without precise VLT information, it can be challenging to ensure compliance with UK window tinting laws.

Using a Tint Metre as a More Accurate Approach to Checking VLT

For a more precise measurement of your window tint’s VLT, consider using a tint metre. This handheld device is designed to measure the amount of light that passes through your vehicle’s windows. It provides an objective reading, allowing you to easily compare the results with the legal requirements.

While purchasing a tint metre is an option, it is often easier and more reliable to visit a professional window tinting company or MOT testing centre. These professionals use calibrated equipment similar to what law enforcement uses during roadside checks.
